Please help ID spinning white worm

[copenhagen_cowboy@live.co]

After I shut the lights out tonight I noticed a white worm swimming in my tank, just spinning around like a ball of fury. Stretched out I would guess he would be about 4". Probably only a couple mm in diameter. No other coloring just white but I think just the tip of one end it more of a transparent white. I scooped it out and have it in a hob breeder box untill I can I'd if its reef safe. Thanks

picture would help-but it sounds like a type of peanut worm

Not sure exactly what those are but I have seen lots of stuff like that on night dives. I think they are trying to capture "plankton" and I doubt they would be a threat to your reef.
But as stated an ID is pretty hard without a good picture.
